Meteoros, detritos espaciais, desentendimentos entre especialistas. O que este editor quer saber é o que é esse orbe azul seguindo a trajetória dos bólidos.
Residents of several states in the Brazilian Northeast saw and filmed the appearance of many lights similar to fireballs, at the sky, at first hours down of Saturday, December 23, 2023.
The images published in media don't come from Space Agencies. It was on social media that videos appeared recording the phenomenon that was observed in the states of Rio Grande do Norte, Pernambuco, Alagoas, Sergipe, Ceará and Bahia. However, there is no consensus among experts about the nature of the phenomenon.
Although the Royal Museum of Greenwich announced the appearance of meteors, called Ursids, coming from the cosmic quadrant of the star Beta Ursae Minoris (Kochab), in the constellation Ursa, after the phenomenon occurred, other experts claim that there are no meteors there: the the lights are just the result of friction from space junk entering Earth's atmosphere.
According to the Brazilian Meteor Monitoring Network (Bramon), this trash is the result of the disintegration of the module of a Chinese rocket launched in January 2018.
Physic and Astronomy professor Ednardo Rodrigues explained that in a meteor shower, the tracks "are thin" because they are made of comet dust. Furthermore, the event is very fast in its visible passage across the sky. In contrast, space junk debris is slow. Its passage can last several minutes.
About the delay in the return of space debris in relation to the launch - after all, it has been almost six years, the professor states that discarded rocket projects can remain "several years in space".
